If the mtz file to be used for reference data set creation contains three digit reflection indices with negative signs (e.g., -102), the output from the original script will not be recognizable to XDS due to lack of space between reflection indices. An alternative method using mtz2various (below) avoids this issue.
{code}
- !/bin/bash
- starting mtz needs to be named refine.mtz with an F column called FP and a SIGF column called SIGFP
